rates, err := exrates.Latest("USD", nil)
if err != nil {
    // Treat error.
    return
}
// Get specific exchange rates.
// rates, err := exrates.Latest("EUR", []string{"USD", "CAD"})

fmt.Printf("Exchange rates for %s on %s\n", rates.Base, rates.Date)
for currency, value := range rates.Values {
    fmt.Printf("%s: %f\n", currency, value)
}

date := time.Date(2019, 3, 8, 0, 0, 0, 0, time.UTC)

// Get all available exchange rates.
rates, err := exrates.On("USD", date, nil)
if err != nil {
    // Treat error.
    return
}
// Get specific exchange rates.

fmt.Printf("Exchange rates for %s on %s\n", rates.Base, rates.Date)
for currency, value := range rates.Values {
    fmt.Printf("%s: %f\n", currency, value)

start := time.Date(2019, 1, 1, 0, 0, 0, 0, time.UTC)
end := time.Date(2019, 4, 22, 0, 0, 0, 0, time.UTC)

// Get all available exchange rates.
days, err := exrates.Between("USD", start, end, nil)
if err != nil {
    // Treat error.
    return
}
// Get specific exchange rates.
// days, err := exrates.Between("EUR", start, end, []string{"USD", "CAD"})

for _, day := range days {
    fmt.Printf("Exchange rates for %s on %s\n", day.Base, day.Date)
